Abstract

The effect of environmental conditions on megaspore germination of A. microphylla 418 were determined by selecting floating megaspores and introducing them to different temperatures, pH, media, P levels, salinities, light, dark and light intensities. Germination was established when indusium cap was pushed aside by the emergence of the first leaf at the shooting stage. Percentage germination was computed. Statistical analysis showed that temperature, pH, medium, salinity and light have significant effects on the megaspore germination of A. microphylla 418. Significantly, high megaspore germination was observed at 30°C, pH of 6, so. 1 with tap water medium, minimum amount of salt and in the presence of light. P level and light intensity are not critical prerequisites for germination since megaspore germination of A. microuhyila 418 under different concentration of Phosphorous and intensities of light was not clearly different based on statistical analysis.
